Mount Polley operations have been suspended, and as of May 31, 2019, the mine is on care & maintenance status. A resumption of operations is anticipated once the economics of mining at Mount Polley improve.

Extensive remediation work in the areas affected by the 2014 breach has been achieved during the past five years. The mine’s closure will not impact the ongoing environmental monitoring and remediation programs.
